2026 March On Challenge

Support my challenge to prevent veteran suicide and save lives

Right now in Australia, at 42%, suicide is the leading cause of death for ex-serving males aged under 30 years old.

So, this March, I am walking to support Soldier On's mental health services and programs to help prevent veteran suicide and save lives.

It would mean so much to me if you donated to support my challenge so that we can show veterans and their families that they are not alone... we stand strong with them.

Together, let's help our heroes march on.

Thanks so much for your support.

So far, I have helped provide:

78

peer support
sessions

74

employment
support

4

psychology
sessions

...to support the mental health of our brave veterans to help them march on.
