Drawing from a robust dataset of Australian advertising, Bigdatr analysed the advertising strategies of the Big4 in Banking & Finance—Commonwealth Bank, NAB, Westpac and ANZ’s multimillion-dollar investments.
The decisions these industry giants make in advertising often serve as benchmarks that influence consumer behaviour and open up or limit market opportunities for other competitors. Our report captures an intriguing development in January 2023: an emerging player took advantage of the industry’s seasonal investment decline during the holidays and looked to disrupt ANZ’s growth in 2023.
This summary provides media mix insights into trending media channels—both online and offline—as well as key industry sectors like Home Loans and Business Banking, helping to demystify the advertising strategies of the Big 4.

This in-depth analysis serves as a benchmark for evaluating your brand’s media value and creative effectiveness against industry leaders. The complete insight report with Media Value and Advertising Creative trends is available on request here.
Top Categories Insights
Home Loans
The housing market is more volatile than ever, making Home Loans a competitive battleground among the Big 4. CBA and Westpac are leading the charge, targeting niche markets like the self-employed and healthcare professionals. They are focusing on personalised creatives to attract financially savvy customers.
Corporate Branding
NAB and CBA are investing heavily in Corporate Branding to solidify their presence on large media platforms. Their creatives focus on community enrichment and women in sports, seeking to build trust and emotional engagement with their audience that build their brand to be more than just a bank.
Barriers to Entry
To rank among the top 4, your brand would need an estimated media value of over $30M annually. This high barrier makes it a tight race, with Tyro emerging strong in January 2023 by capitalising on reduced spending by the Big 4 during the holiday period.

Creative Strategies Across Categories
Business Banking
NAB, ANZ, and CBA are vying for the Business Banking sector, with a special focus on Agribusiness. Their creatives offer ‘expert’ advice and business overdraft features aimed at small to medium-sized enterprises.
Online Banking
As the digital transformation accelerates, Online Banking is gaining traction. ANZ leads in media value, targeting a broad demographic. Westpac and CBA have seasonal strategies focused on the holiday season and the financial calendar, respectively.
Home Loan
This industry category has witnessed innovative creative strategies as the Big 4 seek to dominate this high-value category. Here’s how they’re doing it:

Both Westpac and CBA are making concentrated efforts to tap into niche markets. For instance, CBA ads targets the self-employed, while Westpac ads aims to attract nurses and midwives, filling a gap in a largely underserved market.

Westpac and NAB have introduced ‘offset accounts’ in their Home Loan creatives. This feature aims to attract financially savvy customers by allowing them to reduce their mortgage interest.

Emotional Storytelling
Offline channels like Free-to-air TV in Metro Australia offer an opportunity for emotional storytelling. Looking at FY23 media value trends, Westpac and NAB are seizing key financial periods to capture audience attention.
The Billboard War
Out of Home advertising remains a key channel for Australia’s Big 4 banks to reach and engage their audience. This form of advertising is particularly effective for capturing eyeballs in high-traffic areas, combining the power of static and digital billboards to maximise visibility.
Commonwealth Bank is going big by advertising on the largest billboard in the southern hemisphere for brand building. While their ‘book an appointment’ call-to-action is a straightforward yet effective way to capture high-intent leads in the home lending segment.
ANZ, top 3 on this media channel, continues to push their ‘Financial Wellbeing’ campaign message through this channel, empowering consumers to take more control over their personal finance using ANZ’s online banking solutions.
