Nicole Parker, who said she bought a house at age 20, said it's not just about avocado on toast. She said people need to make smarter choices.
"You can't have a nice car, student loan, regular alcohol consumption, travel regularly, branded clothing, new iPhone, not worry about saving power, $12 bakery quiches AND brunch.
"It's all about choices. How much you want a home (& how soon) will affect your choices. Take your pick, do what works for you, don't blame someone else for your poor saving ability & notice that $22 does add up. 11 years is a long time but some people will go 11 years & still not have a house - then they might actually regret not cutting the brunch once a week."
Another Facebook user, Kaylee Belford, said: "Basically if you don't eat or go anywhere for 10 or so years then you might be able to get a house loan. But then the prices of houses have risen so much the amount you've saved still isn't enough. If you don't have something to sell or an inheritance just forget it."
Tina Lunn said: "The quickest way to save money is to make your own lunches, stay home in the evenings & cook, restrict your daily cafe coffees to a weekend with family & friends and limit take outs as a treat. Stop buying clothes you really do not need. You will be surprised how much you can save in a year! I hear you yes but my friends have just bought the latest this & that, so what, do they have a deposit for a house after a few years of self discipline?"
Karyn Murray said: "Anybody thought about getting a second job to pay for your first home? That's how we did it, despite 18% mortgage interest. We were too bloody exhausted to go out - but it didn't last forever."
Kiwis also responded to Salt's hot take on the issue on Twitter.
The avocado industry has since defended young people's rights to chow down on a plate of smashed avocado.
"I'm glad they're eating avocados, at least they have the good sense of putting something nutritious down their throats," Avocados Australia chair Jim Kochi told AAP. "Why didn't he pick on coffee - where's the nutrition in a cup of coffee or slug of alcohol?."
