Moves to slap GST on overseas online shopping purchases worth less than $1000 will be on the agenda when Federal Treasurer Joe Hockey meets his state and territory counterparts this week.

However, the states and territories will need to argue the case for a lower GST threshold on foreign imports, the federal government says.

Flight Centre is still a formidable competitor, on price and a 'value-add' service.

The treasurers will meet in Canberra on Wednesday from 8.30am for the Standing Council on Federal Financial Relations, the first since the change of government.

A spokeswoman for Mr Hockey said the meeting will focus on economic growth and ways to increase productivity.
