Derrinallum is the next and very small town heading west towards Hamilton. There is more to this town that might be gathered in a first impression. The tree lined main street avenue was planted 100 years earlier and is quite impressive. So too the churches are centurions
The town is the centre for the surrounding farming community and lies at the foot of Mount Elephant.
Mount Elephant is a 240 m high conical breached scoria cone formed by an extinct volcano.
The Post Office opened on 7 December 1868 but was named Tooliorook until 1873. There is no reason for the change or for where Derrinallum is derived.
