'No surprise - tune in at 7.30pm tonight,' he said when asked about the border ban.  

Mr Frydenberg said though it was 'hard to be precise in the middle of a pandemic'.

'There's a lot of uncertainty, globally and domestically with respect to the virus,' he said.

'The key point is, we'll always follow the medical advice and we'll always do our best to keep Australians safe.' 

Prime Minister Scott Morrison said on Saturday Australia was still pursuing a Covid-19 suppression strategy and refused to say when the borders would re-open.  

Health Minister Greg Hunt meanwhile said the nation would implement a three-step plan to gradually remove the onerous restrictions.  

Firstly, the government will identify 'safe countries' with low levels of Covid-19 and set up travels bubbles similar to the current arrangement with New Zealand.

The second step is to offer the whole adult population a vaccine and the third step is to allow vaccinated Aussies to go on holiday.

'It's really built around the three principles of green lanes and opening up new bubbles with different safe countries, as we've done with New Zealand and as we'll do with others in the Pacific and in the region as they become progressively safer,' Mr Hunt said on Sunday.

'The second part of the road map is our own domestic vac­cination strategy, protecting the nation.

'The third element, that's the capacity for greater travel for those who have been vaccinated.'

Mr Hunt said that vaccinated Aussies can travel earlier' and 'return with lesser restrictions'.
