ummm, its... ok... if you know where the supercheap/harvey norman is then follow this.... dirctly across from SC/HN (facing the river there is AAMI and a resturaunt, between them is a little street called CANAL ST go down there there is a turning circle and a carpark you will see the overpass well thats where we are..

OR....

as you come into launceston via the southern outlet follow the road,
all the way past office works
stay in the middle lane
go right at the "Y" you should now go under the overpass,
turn left (SC/HN on your right)
now before AAMI turn left again
We are down there....

Hope that helps
