Christine Watson, Kylie Byrnes, Lisa Nutley and Anita Morrison were one of less than half the starting groups to complete the torturous 100 kilometre trek that begins in the township of Brooklyn on the Hawkesbury River and winds through Ku-ring-gai Chase National Park before finishing at Georges Heights Oval in Mosman.

In an amazing accomplishment, Team Walkie Talkies finished 20th for ladies teams and 249th in the overall teams section out of 556.

The team battled wet and wild conditions which included climbing boulders, crossing approximately 10 flooded fast flowing creeks while desperately holding onto overhead ropes, scaling rock ledges with ropes and walking for 33 hours with only several short stops.

Sleep deprivation also contributed to the toughness of the task.

All four ladies finished with no injuries other than a few bumps, bruises, blisters and plenty of muscle soreness. 

Going into the event, none of the Walkie Talkies expected to finish but proudly did so. 

Oxfam Trailwalker is one of the most inspiring team challenges in the world in support of people living in poverty around the world.

After the start on the Hawkesbury and through The Ku-ring-gai Chase National Park, the trail then winds its way through the northernmost reaches of Berowra Regional Valley Park, presenting walkers with the greatest challenges of the event. while they are fresh.

The trek has many twists, turns, ascents and descents along the rugged bush tracks of the Mt Ku-ring-gai, Bobbin Head, Sphinx, and Warrimoo trails before reaching Garigal National Park. 

It then traverses the Harbour to Hawkesbury Walking Track (in reverse) as it follows Middle Harbour Creek from its beginnings into Middle Harbour proper. 

The final kilometre rewards trekkers as they walk high above Sydney Harbour looking out through Sydney Heads, before the triumphant finish in Mosman.

Only 37 per cent of teams finished with all four walkers completing the trail which took 32 hours and 50 minutes on average.

Out of the 2,224 walkers to start the event, only 1,496 (67%) finished the full 100 kilometres, making Walkie Talkies’ effort all the more amazing.
