I can recommend a place in Melbourne if you are interested, I had mine repaired there.

It can be a bit pricy and it may not be worth it if your boots are not great. I justified it for my boots as I loved them and knew that the chances of me
a) finding a pair I liked to replace them OR
b) finding the time to find that elusive pair
was going to be slim to none. The way I looked at it was that the cost of the refurb was steep, but cheaper than the cost of new boots. I have had 2 more seasons out of the refurbed boots now, so worth it in my opinion.

Only problem is that they will need to be left for repair which means two trips for you...

ETA: Errol St, North Melbourne to be more precise if you are wanting to avoid the city. At least it is on the right side of town from woodend and there is good coffee in the vicinity!
