Back Roads continues the journey on the challenging Strzelecki Track, heading up to Innamincka in the top corner of South Australia. Heather Ewart finds out what it takes to survive a job on this remote and historic track.

Guest presenter Lisa Millar takes us on a journey along Victoria's spectacular Great South West Walk. Hiking the 250km trail is a chance to connect with nature but, as Lisa discovers, the experience can also be life changing.

Heather visits the sleepy Victorian mountainside town of Walhalla, on the historic Goldfields Railway. Frozen in time, with movie-set looks, a cricket pitch that defies logic, and nearby creatures straight from the Dreamtime.
