Chris Eyre is the great-great grandson of explorer Edward John Eyre, who in 1841 became the first man to cross the Nullarbor Plain and connect by land the remote settlements of Port Lincoln and Albany.

After months of planning and preparation, the six arrived in Australia and started their journey last week at Eyre's Waterhole near Streaky Bay.

Chris Eyre said at the waterhole:"It's just surreal to be standing in the same spot that my great-great grandfather stood and look at the water source that saved not only his expedition, but subsequent expeditions - it's just such a spiritual feeling."

The group were feted at a community reception on Thursday evening at Streaky Bay before being escorted to the edge of town by Streaky Bay Area School students on Friday morning.

Chris told the reception on Thursday that the group were "overwhelmed" by support they have received from the community, and any problems they came across had been met with a 'no worries' from locals and the problem fixed.

They are raising money for the Oxfam and Save The Children charities as they walk.

They stopped overnight at Haslam and Smoky Bay on their way to Ceduna where they spent Monday resting up and doing their washing.

"The rest day was a Godsend, but our feet are holding up well," Chris said Tuesday morning as they headed west for an overnight camp spot on the way to Penong today.

"It's Sod's law," he said as he eyed dark clouds gathering ahead of the group. "We didn't think we would need our wet weather gear once we got here so it's at the bottom of our packs."

Chris is fulfilling a life-long ambition in retracing some of his great-great grandfather's 1841 expedition.

The plan is to walk the 640 kilometres from Streaky Bay to Eucla and to arrive there on July 7, the same day that Edward John Eyre arrived in Albany 167 years before.
