When the lockdown happened, Canberra bottleshop owner Matthew Farrah saw his trade rise.
The owner of Farrah's Liquor Collective in Fyshwick said online sales soared.
The pattern was that when pub doors locked, people got home deliveries instead.
"People really did jump on the website and bought," he said.
The lockdown may have accelerated a trend that was happening anyway - home drinking.
An anti-alcohol abuse campaigning group has just published its annual survey of tippling habits and found that three-quarters of Australian drinkers drink mostly at home.
The Foundation for Alcohol Research and Education also found that two-thirds of Australians who drink "had the largest quantity on one occasion in the past 12 months in the home".
The days of the pub being the dominant watering hole have gone, the findings of the organisation's Annual Alcohol Poll for 2020 indicate.
But there is deep disagreement about whether home drinking is a good or bad thing.
The drinks industry said that the FARE organisation was stating the blindingly obvious and trying to scare people.
"The real question is so what?" Alcohol Beverages Australia head Andrew Wilsmore said.
"There is nothing wrong with drinking at home or using a delivery service. In typical FARE fashion, innocuous facts are used to try and create community concern when there is no evidence to suggest that people should be concerned.
"Australians overwhelmingly enjoy a beverage at home as this is where most drinking occasions occur - a glass with dinner, chilling over a movie, hosting family and friends to a meal or BBQ, or watching sport on TV with a few mates."
FARE chief executive Caterina Giorgi said drinking in the home was a longstanding trend that had since intensified.
"Despite what many of us assume, people who drink alcohol are more likely to do so at home," she said.
This was the case for young and old and was independent of the lockdown.
But FARE is worried that people think home drinking is not particularly harmful.
"Drinking in the home is widespread, yet we don't often think about the harms from alcohol occurring in the home because they're largely invisible," Ms Giorgi said.
"Alcohol increases the severity and frequency of family violence and contributes to a range of cancers and alcohol dependence."
However, there is recent evidence that credit card spending on booze has actually fallen.
