Gillisons IN Australia

I am descended from a sister of Reverend Andrew Gillison (1868-1915), who emigrated in 1905 from Scotland to Australia. He later went as a military chaplain to Galipoli, where he was shot dead as he tried to save a wounded soldier. He has many descendants in Queensland, NSW and elsewhere and if any of them (or anyone else) is interested in their Scottish roots I can certainly give them information.
