People in Brisbane's CBD are spending a at least $4.4 million a month on fast food and restaurants, according to a survey.
The Commonwealth Bank research found its customers in Queensland were spending an average of about $82 each per month on fast food and $118 on dining at restaurants - the third highest spend on both fast food and restaurants nationally.
The research also found CBA customers across Australia were spending more than $640 million a month on fast food and restaurants combined.
In Queensland, the suburb with the second highest fast food and restaurant spend was South Brisbane, with a spend of $1.35 million. In third was Surfers Paradise, at $1.3 million, then Fortitude Valley ($1.3 million), Broadbeach at $1.22 million, and Southport at $1.12 million.
It was regional Queensland centres that had the highest CBA spend on fast food - the mining town of Mount Isa coming in at fifth nationally with their customers spending an average of $71 a month.
Port Douglas and Palm Cove also had a high monthly spend on restaurants, at $157 and $144 respectively.
Commonwealth Bank digital executive general manager Pete Steel said that while people aged under 30 made up almost half of all fast food purchases and a third of restaurant trade, they were not the ones spending the most money.
“Customers aged 40 to 45 spend the most per month on fast food, potentially because they are purchasing meals for a family," he said.
"While those aged between 50 and 55 spend the most in restaurants - $184 a month on average.
“Interestingly, spending on groceries has remained fairly flat, only increasing by 2 per cent in the last two years."
