In Treasurer Scott Morrison's budget speech he promised to "ensure the government lives within its means" and warned "this is not a time to be splashing money around".
Shortly afterwards, he hosted an invitation-only party, which cost taxpayers $11,625 for food and drinks. This is more than even Joe Hockey spent on post-budget parties.
In all, the Treasurer spent $4620 on a selection of hot and cold canapes, $5445 on alcohol, and $560 for eight wait staff to cater the 90-minute function for 100 people.
The Treasurer's gathering is a post-budget taxpayer-funded tradition, but the documents show Morrison's party cost more than previous Treasurers had spent.
