You also have to consider in the future - the potential of damage from large branches which may fall in winds, and the fruit, which may spread seed (here it is by birds and flying foxes - fruit bats).

OK but if you still want the tree, then yes they are quite tough, and after dropping leaves, should forms new shoots again once it has recovered from transplant.

Once established, growth is dependant on many factors including soil type and depth, fertilizer etc, but growth would soon be in terms of feet per year, not cms.

I live on Moreton Bay and this magnificent fig tree grows naturally here into a giant in this summer rain, subtropical, no frost environment. I planted other figs at the local Schools because the Moreton Bay fig was too big for a spare 0.5 hectare.

1. 25 metres radius canopy up to 50m, because it has 20 cm stilt roots from lower limbs at 15m from trunk. Expect root spread 150 m here.
Growth at 3 years circa 1m+ per/annum here.
Mini cyclone in 2006 blew over a 119 year old relative 40 m height at local school, because of root restriction.

There is a smaller relative "Ficus platypoda" for smaller spaces = 5m in 18 years and 4m radius but you are in a winter rainfall cold climate and these tree are inclined to be xenophobic i.e they don't like strange environments.
There must be better species for you.
