But City of Launceston mayor Albert Van Zetten says a staged approach to the upgrade could have UTAS Stadium fitted with a rectangular configuration within the 30-month deadline.

Plans to be discussed at next week's council meeting include a $108 million seating upgrade that features retractable seating in redeveloped northern and eastern stands.

Cr Van Zetten said the project as a whole would take at least three years to complete once given the all clear, but indicated parts of the plan could be in place in time for the World Cup.

"That's going to take quite some time obviously - the first stage is getting it through council this coming council meeting and then it's working with the state government," Cr Van Zetten said.

"You'd be talking a three-to-five year plan to see it through to everything being done, and that's going to depend on funding from state and federal government.

"It could be done in stages and that's something else we've looked at - part of that could be done by 2023 and that would be really more for the soccer, and that would depend again on funding."

UTAS Stadium is one of 13 venues across Australia and New Zealand bidding to host World Cup games, and one of four that currently fall short of FIFA's minimum requirements.
