The prime minister’s office spent more than $15,000 on a new oven in the parliament house cabinet suite.
Information tabled by the Department of Parliamentary Services confirms a total of $15,535 was spent on the oven, including $13,490 on its manufacture.
The installation occurred in May last year, when Tony Abbott was still prime minister.
The department said the appliance replaced a 24-year-old oven that was not repairable and presented a health and safety risk for chefs using it.
During a Senate estimates hearing earlier this year, the department secretary Robert Stefanic said $15,000 was not an unusual cost for a commercial oven and not at the upper end of pricing.
The former prime minister has been known for getting a good deal, especially when it comes to appliances.
In December last year, his purchase of a second-hand fridge on Gumtree made news in the Australian media, when he arrived at the house of Emmanuel and Emily Hastings, in the Sydney suburb of Newport, to collect the large fridge his wife had bought on the trading website.
