Prime Minister Scott Morrison is keeping mum on the election date, saying he is focused on explaining his government's budget to the public.
He had been widely tipped to announce a May 11 election on Sunday, but that did not happen and he is instead spruiking last Tuesday's budget announcements.
The delay has led to accusations from the Labor opposition that Mr Morrison has pushed the election back so the cash-strapped coalition parties can exploit taxpayer-funded advertising.
"Bill (Shorten) can be as frustrated and anxious and grumpy as he likes, but you know, we are running to the plan that we've set as a government," Mr Morrison told reporters in northwestern Sydney on Sunday.
"We're looking forward to the weeks ahead and it won't be before too long that obviously we will go to the polls."
He dismissed the complaints about spending taxpayers' money to promote the budget.
"I'm also not going to take lectures from the Labor Party that completely defied every single convention that has been known to Australian elections when they ran taxpayer funded ads during the 2013 caretaker period."
He said the three dates of May 11, 18 and 25 still stood.
"The election will be called in April and the election will be held in May," he said.
"We're not doing this with any haste and we're not doing it with any delay."
