Australia’s software sector in late 2024 is a dynamic marketplace where just a few brands dominate the everyday digital experiences of millions. In Q4 2024, Microsoft 365, Google Search, and Gmail stood out not merely as household names, but as technological titans shaping how Australians communicate, collaborate, and discover information. According to newly released data from Sensor Tower, these brands not only capture staggering audience numbers in both web and app ecosystems, but also reveal evolving strategies around user engagement and digital advertising. This article critically examines the cross-platform performance, distinctive user trends, and the evolving competitive tactics of these leading software brands in Australia.
Microsoft 365 has long enjoyed a reputation for ubiquity in both corporate and personal spheres, but Q4 2024 data points to new nuances in Australian user behavior. Microsoft’s digital ecosystem incorporates everything from classic portals like office.com and onedrive.com to collaborative tools found at teams.microsoft.com and a suite of native applications on desktop and mobile. This integrated experience is mirrored in strong engagement and retention patterns.
This surge underscores Microsoft’s ability to nurture deeply ingrained user habits, especially among knowledge workers and enterprise teams. However, as employee work styles evolve, with hybrid and remote models persisting, it’s essential to distinguish between necessity and true user preference—a subtlety not always captured in aggregated traffic tallies.
What merits closer scrutiny is Microsoft Teams’ subtle decline. Monthly active users tapered to about 1.7 million by December. This drop mirrors broader post-pandemic adjustments as organizations recalibrate from video-heavy remote work routines toward hybrid collaboration. While not indicative of a mass exodus, it’s a trend that suggests the Teams franchise may need fresh innovation or repositioning to maintain momentum in a market saturated with collaboration contenders.
The brand’s advertising effectiveness, however, is difficult to quantify without conversion and ROI figures. Sensor Tower’s data, while authoritative in tracking spend and impressions, doesn’t directly illuminate whether these marketing dollars resulted in new sign-ups, deeper engagement, or successful upselling initiatives.
A moderate risk surfaces in the decline of Microsoft Teams usage, illustrating how even deeply embedded enterprise products are subject to disruption by shifting work patterns or superior user experiences elsewhere. Ensuring that Teams—and the broader Microsoft 365 suite—continuously evolves to reflect changing needs will be crucial.
A less-publicized standout from the quarter was the web incarnation of Google Lens. October saw visits spike to 312,000, a sign that Australians increasingly complement traditional text searches with visual queries. This hybrid search behavior is in step with global trends toward multimodal discovery and underlines Google’s capacity for quiet innovation even in seemingly mature services.
It’s important to contextualize this: Google’s SEO and app store strategies, combined with deep device and browser integrations, may obviate the need for aggressive paid outreach that more niche or challenger brands require.
The rise in Google Lens usage offers a window into the future, though. As multimodal and AI-driven searches become mainstream, Google’s ability to seamlessly integrate cutting-edge features without overwhelming users will determine its longevity atop the search hierarchy.
At the same time, Gmail’s mobile app reached a peak of approximately 7.7 million monthly active users in November. This slight but steady increase speaks to the app’s role as the default choice, prized for its speed, reliability, and integration with broader Google services.
The monthly deduplicated audience—combining web and app—held above 15 million, a figure that cements Gmail’s position as one of the most widely used software brands in the entire Australian market.
However, this strength also breeds complacency. Dominance can dampen urgency to innovate or respond quickly to emergent competitive threats. For example, Microsoft’s heavy ad investments signal a hunger to maintain top-of-mind status, but sustained market leadership will require more than just spend—it demands continual reinvention of user experience and cross-app synergies.
Google’s cautious approach to paid advertising, while signaling self-assurance, could also risk missing segments of the market ripe for persuasion or onboarding into newer, less mature services. Similarly, Gmail’s fundamental stability could turn into a liability if communication paradigms shift quickly (for example, toward federated or encrypted messaging).
A potential risk for all three is exposure to regulatory and privacy shifts. Australia’s tech regulatory environment remains volatile, with heightened oversight of data practices and market concentration. Any enforced changes could impact default settings, user tracking capabilities, or even the core monetization practices of these software giants.
Brands reading into these findings will need to balance short-term tactical shifts with long-term bets on platform inclusivity, privacy-first design, and adaptable workflows—priorities that increasingly define success in the maturing digital software ecosystem.
For Microsoft, innovation in collaboration and streamlined, context-aware productivity will be vital—especially as competitors from both Europe and Asia eye the Australian business market. Google must guard its search franchise by doubling down on privacy, speed, and multimodal discovery. Gmail, steadied by inertia, must not mistake loyalty for insulation from disruption.
Yet, the market pulse should be read with humility. In the fast-changing Australian tech ecosystem, even the most established names can find themselves one disruption away from reinvention—or obsolescence. By blending cross-platform insights, balanced advertising, and a strategic openness to change, digital leaders in Australia will secure their place in the nation’s connected future.

Microsoft 365: The Multi-Platform Productivity Powerhouse
Microsoft 365 has long enjoyed a reputation for ubiquity in both corporate and personal spheres, but Q4 2024 data points to new nuances in Australian user behavior. Microsoft’s digital ecosystem incorporates everything from classic portals like office.com and onedrive.com to collaborative tools found at teams.microsoft.com and a suite of native applications on desktop and mobile. This integrated experience is mirrored in strong engagement and retention patterns.Consistently High Audience Reach
Throughout Q4, the monthly deduplicated audience for Microsoft 365—spanning web and app—held firm above 2.7 million. Crucially, this figure demonstrates not just sheer reach, but customer stickiness, with users likely accessing multiple ports of entry during a typical month. Office.com, a key campus for both legacy and new users, registered particularly active engagement, with visits per unique visitor in October peaking at an impressive 52.This surge underscores Microsoft’s ability to nurture deeply ingrained user habits, especially among knowledge workers and enterprise teams. However, as employee work styles evolve, with hybrid and remote models persisting, it’s essential to distinguish between necessity and true user preference—a subtlety not always captured in aggregated traffic tallies.
App Engagement: A Mixed Pattern
Focusing on core apps, Microsoft Outlook for mobile continued to display remarkable stability. Monthly active users hovered around 5 million—an achievement for a communications tool amidst fierce competition from native email clients and other ecosystem players. Similarly, flagship productivity offerings like Microsoft Word and Microsoft Office maintained steady engagement, each boasting between 290,000 and 300,000 active monthly users.What merits closer scrutiny is Microsoft Teams’ subtle decline. Monthly active users tapered to about 1.7 million by December. This drop mirrors broader post-pandemic adjustments as organizations recalibrate from video-heavy remote work routines toward hybrid collaboration. While not indicative of a mass exodus, it’s a trend that suggests the Teams franchise may need fresh innovation or repositioning to maintain momentum in a market saturated with collaboration contenders.
Facebook: The Core Advertising Channel
Microsoft’s digital advertising activity in Australia reveals a pronounced focus. During Q4, monthly ad spend on Facebook alone soared over $24,000 in September, resulting in over 5 million impressions. This heavy investment in social media, contrasting with relatively muted spend on other platforms, signals both the prioritization of broad visibility and an attempt to reach users in their “off-hours,” outside email and spreadsheet silos.The brand’s advertising effectiveness, however, is difficult to quantify without conversion and ROI figures. Sensor Tower’s data, while authoritative in tracking spend and impressions, doesn’t directly illuminate whether these marketing dollars resulted in new sign-ups, deeper engagement, or successful upselling initiatives.
Strengths and Risks
Microsoft 365’s key strength remains its deep integration across professional and personal use cases, coupled with high audience regularity in both web and app environments. Its advertising presence fortifies brand awareness, though overdependence on platforms like Facebook introduces vulnerability to shifting digital ad market dynamics and privacy policy changes.A moderate risk surfaces in the decline of Microsoft Teams usage, illustrating how even deeply embedded enterprise products are subject to disruption by shifting work patterns or superior user experiences elsewhere. Ensuring that Teams—and the broader Microsoft 365 suite—continuously evolves to reflect changing needs will be crucial.
Google Search: The Unrivaled Gateway
No other service captures the daily digital habits of Australians quite like Google Search. Its reach is foundational to online navigation, a fact reinforced by Sensor Tower’s Q4 2024 findings. But beneath the surface, Google’s engagement dynamics reveal a company intent on maintaining relevance even as discovery habits diversify into apps and AI-infused assistants.Massive Cross-Platform Audience
Google.com’s Q4 audience figures are almost unrivaled. Unique monthly visits routinely exceeded 16 million—a scale that feels less like a web platform, and more like a digital utility. This absolute dominance reinforces Google’s role as the default starting point for a wide array of user intents, from information retrieval to shopping and news consumption.A less-publicized standout from the quarter was the web incarnation of Google Lens. October saw visits spike to 312,000, a sign that Australians increasingly complement traditional text searches with visual queries. This hybrid search behavior is in step with global trends toward multimodal discovery and underlines Google’s capacity for quiet innovation even in seemingly mature services.
App Engagement: Growth Trajectory
On Android and iOS, the Google app maintained a robust momentum. By December, monthly active users had climbed beyond 5.5 million, up steadily over the quarter. This signals not just desktop-to-mobile migration, but the enduring relevance of Google’s all-in-one feed, search, and assistant functionality. Google Lens’ app showed modest but sustained growth, reflecting the expanding appetite for AI-powered search paradigms among Australian smartphone owners.Advertising: Minimal, but Targeted
Perhaps the most surprising aspect of Google’s Australian strategies is the brand’s comparatively modest ad spend. Across Q4, direct ad investments were minimal, with a noteworthy campaign on Reddit peaking in December and generating only about 3,500 impressions. This hesitancy to saturate the marketplace with paid ads could stem from Google’s entrenched organic dominance or a deliberate strategy to differentiate paid messaging from organic cross-sell.It’s important to contextualize this: Google’s SEO and app store strategies, combined with deep device and browser integrations, may obviate the need for aggressive paid outreach that more niche or challenger brands require.
Strengths and Risks
Google Search’s unmatched web presence is its greatest strength: for most Australians, online life begins and ends with Google. Yet this scale is a double-edged sword. Regulatory scrutiny—in Australia, as elsewhere—remains an ever-present risk. New mandates on data privacy, antitrust investigations, or requirements for greater transparency in advertising could all shift Google’s cost of doing business or restrict formerly frictionless integration opportunities.The rise in Google Lens usage offers a window into the future, though. As multimodal and AI-driven searches become mainstream, Google’s ability to seamlessly integrate cutting-edge features without overwhelming users will determine its longevity atop the search hierarchy.
Gmail: The Indispensable Communication Anchor
Even in an age of disposable team chats and DM-centric communication, Gmail continues to anchor digital correspondence for both consumers and businesses in Australia. In Q4, Gmail’s cross-platform data tells a story of unwavering relevance and subtle but significant adaptation.Stable Web and App Engagement
Gmail’s footprint is most acutely felt through mail.google.com, the central hub for millions of users. Monthly unique visitors consistently topped 6 million, with an outstanding average of 64 visits per user—a testament to how integral email remains to everyday productivity.At the same time, Gmail’s mobile app reached a peak of approximately 7.7 million monthly active users in November. This slight but steady increase speaks to the app’s role as the default choice, prized for its speed, reliability, and integration with broader Google services.
The monthly deduplicated audience—combining web and app—held above 15 million, a figure that cements Gmail’s position as one of the most widely used software brands in the entire Australian market.
Organic Growth Over Ad Spend
A compelling facet of Gmail’s Q4 data is its virtual absence from the digital ad market. The brand allocated little to no significant monthly ad spend, reflecting supreme confidence in organic word-of-mouth and ecosystem-driven growth. This channel-light strategy relies on Gmail’s embeddedness within Android and iOS onboarding, as well as the self-reinforcing nature of ‘network effect’ products: people use Gmail because everyone else does.Strengths and Risks
Gmail’s strengths are familiar yet formidable: seamless integration, robust spam filtering, and the trust accumulated from years of reliable performance. The absence of substantial ad spend shows brand strength but also hints at complacency. Even dominant incumbents need to cultivate innovation—be it through smarter inboxes, end-to-end encryption, or enhanced third-party integration—to forestall user erosion from security concerns or next-generation communication rivals.Cross-Brand Comparisons: Trends and Takeaways
The Q4 2024 landscape reinforces that, while Microsoft 365, Google Search, and Gmail are all leaders, their approaches and foundations diverge in instructive ways:- Microsoft 365 relies on enterprise lock-in, habitual usage, and heavy Facebook ad investment to sustain engagement and acquire new users. The chief vulnerability is around usage declines in specific segments (Teams), suggesting risk if work patterns shift dramatically again.
- Google Search wins by sheer audience volume, resource-light advertising, and continuous, subtle innovation in AI-powered tools like Lens. Regulatory uncertainties and the challenge of keeping search experiences fresh as discovery methods evolve are the primary threats.
- Gmail sustains dominance thanks to deep platform integration and relentless utility, needing neither heavy advertising nor regular reinvention. Its strategic risk lies in the potential for stagnation, especially if disruptive communications platforms or privacy-centric competitors gain critical mass.
Critical Analysis: Where the Leaders Shine and Lag
A defining strength of all three brands is their ability to be everywhere their users are—web browsers, desktops, mobile apps, and cloud syncs. Cross-platform reach is no longer “nice to have” but an imperative, and these brands’ investments are paying off in record user numbers and engagement stats.However, this strength also breeds complacency. Dominance can dampen urgency to innovate or respond quickly to emergent competitive threats. For example, Microsoft’s heavy ad investments signal a hunger to maintain top-of-mind status, but sustained market leadership will require more than just spend—it demands continual reinvention of user experience and cross-app synergies.
Google’s cautious approach to paid advertising, while signaling self-assurance, could also risk missing segments of the market ripe for persuasion or onboarding into newer, less mature services. Similarly, Gmail’s fundamental stability could turn into a liability if communication paradigms shift quickly (for example, toward federated or encrypted messaging).
A potential risk for all three is exposure to regulatory and privacy shifts. Australia’s tech regulatory environment remains volatile, with heightened oversight of data practices and market concentration. Any enforced changes could impact default settings, user tracking capabilities, or even the core monetization practices of these software giants.
