As we laid out in last week’s article on Generation X, marketing or conducting research with only the generations in mind is a fool’s errand prone to generalisations.

But that doesn’t mean that there isn’t something to be mined from understanding the social, economic and technological environment people grew up in.

Generation Y, or more commonly Millennials, were for years the marketing shorthand for young, online-obsessed, impetuous consumers – who were eschewing the traditional life milestones of their elders.

Using the Australian Bureau of Statistics definition, Millennials were born between 1981 and 1995. In 2026, that puts them roughly between 31 and 45 years old. No longer the youth of the generations, Millennials are now parents, managers, homeowners, renters, business owners and established professionals – often juggling mortgages or rent, children, ageing parents and increasingly expensive bills.

But like the cohort before (and after them), marketing to Millennials means understanding a generation that grew up alongside enormous social, technological and economic change.

In his podcast, The Blindboy Podcast, the host regularly touches on the dream that Millennials were sold, and how that dream was shattered when Millennials entered the workforce during the 2008 Great Recession, and then experienced subsequent financial disruptions like the COVID-19 pandemic and modern cost-of-living spikes.

This unique experience means that many Millennials have failed to hit the major life milestones like owning a home and starting a family akin to generations before them.

At the 2021 Census, Millennials represented 21.5% of Australia’s population, making them roughly comparable in size to Baby Boomers. However, their lives looked quite different from previous generations at the same age. Among Australians aged 25–39, Millennials were more likely to have been born overseas, more likely to rent and less likely to own a home than Generation X or Baby Boomers had been at the same life stage.

Because millennials struggle to hit traditional milestones of adulthood (like buying a home or starting a family), they experience perpetual anxiety. In his episode Barbie and Mattel as Millennial Pavlovian Conditioning, Blindboy posits that buying nostalgic toys, watching reboots, or clinging to childhood media is a literal neurological retreat to a time before the economic system broke its promises to them.

Brands have jumped to revisit the 1990s and 2000s through fashion, entertainment, food, music and collaborations. For Millennials, these references connect them to a simpler time, before all the realities of adulthood weighed on them.

Because Millennials reached what would traditionally be considered prime earning and spending years at a difficult economic moment, value is a high priority. Deloitte’s 2026 Australian Gen Z and Millennial Survey found cost of living remained the leading concern for both generations (54% of Millennials), with financial pressure influencing major personal and professional decisions. Globally, 52% of Millennials reported delaying major life decisions because of their financial situation.

For marketers, that makes value increasingly important.

Consumers under financial pressure can become more considered about where their money goes. A $150 purchase may still feel worthwhile if the quality, durability or experience justifies it. A $20 purchase can feel expensive if it disappoints.

Brands therefore need to make the value equation easy to understand. What am I getting? Why is it worth it? Will it last? Will it make my life easier, better or more enjoyable? Price remains important. But proving worth is often more powerful than simply being cheaper.

Authenticity is another key brand component for this generation, after hearing brands talk about purpose, sustainability, community and values for most of their adult lives.

Deloitte’s Australian research illustrates how strongly values can influence decisions in other areas of Millennials’ lives: more than 40% of Gen Z and Millennial respondents reported having rejected a potential employer because its values did not align with their own. The implication for brands isn’t that every campaign needs a social cause attached to it. In fact, forced purpose can have the opposite effect.

What matters is consistency between what a brand claims and what people actually experience. Evidence is stronger than adjectives.

Millennials were among the first to embrace social media, smartphones, streaming, online shopping and the platform economy as these technologies became mainstream, so multi-channel communication is a must.

ACMA’s latest communications research shows that social platforms continue to play a significant role among Australians in the Millennial age range. Among 35–44-year-olds, 63% had used Instagram in the previous six months, while TikTok use reached 36% and Reddit 33%.

Having a consistent experience across all channels is a must, as Millennials can discover something on social media, research it elsewhere, read reviews, compare alternatives, and eventually purchase online or in-store.

For Millennials, convenience is an expectation, given they were at the forefront of services that removed friction from everyday life, including: online banking, ecommerce, food delivery, streaming, ride-sharing, and digital booking.

This means that convenience is no longer remarkable, but that friction is much easier to feel. A difficult checkout, unclear delivery information, poor mobile experience, complicated returns process or unanswered customer enquiry can very quickly undermine otherwise strong marketing, or a solid product. This means marketing to this cohort isn’t just advertising; it’s ease of navigation on the website, checkout times, premium-feeling packaging, and seamless delivery.

Good research understands that generation insights act as one layer of understanding, rather than the answer itself.

So, how should brands market to Millennials? The challenge isn’t finding the secret Millennial marketing formula; it’s recognising what has changed.
