NSW Treasurer Daniel Mookhey has said he is “still sore” about the state’s GST carve-up and he will push the re-elected Albanese government to reform the tax’s allocation because the country’s most populous state is “carrying the federation”.

Mookhey made the remarks on Monday at a McKell Institute curtain-raiser for the June 24 budget at which he acknowledged the re-election of the federal government with a “powerful mandate”.
