The town of Bombala was settled in the 1840's, and was one of the major towns of the region. It was the terminus for the railway line from Sydney, which has now been progressively closed all the way back to Canberra. You can still see many historic buildings in the town. The railway station and lines are still there, and you can walk on the platform.
Platypus. The town themes itself as Platypus country and has a platypus reserve around 3km south of the township on the Delegate road. You will need to be there around dawn or dusk in order to see the platypus.edit

The small down of Delegate is 30 minutes drive away. You can continue on the road south from there, for a 100km winding and scenic trip to join the Princes Highway. Great trip for those who love driving corners. Not so great for travelling with those with a propensity for car sickness.
