Where does my fundraising money go?

100 percent of the funds raised through the Kosi Challenge go towards Rare Cancers Australia’s (RCA) work of improving the lives and outcomes of Australians living with a rare or less common cancer (RLC). RCA provides information and support to those diagnosed with RLCs, fundraises for treatment, and fosters a patient community. We also campaign for affordable and accessible life-saving drugs that will help make the current treatment system more equitable.

How do I set up a fundraising page?

You will set up a fundraising page as part of your event registration. It is a simple process and can be done online very quickly. You can then share the link with everyone you know online. If you plan to be part of a team, you can join or create a team as part of your event registration. If you forgot to do this, you can always create or join a team via your fundraiser dashboard.

How much am I expected to raise?

Any amount you raise, no matter how big or small, is appreciated. All fundraising goes to supporting RCA's work with rare cancer patients. And remember – raising public awareness is an important part of the event too, so be sure to share your participation far and wide

Can I register for Kosi Challenge without actively fundraising?

Yes, of course. We welcome as many participants as possible.

Is there a prize for the biggest fundraiser?

We’d welcome the provision of a prize to incentivize our participants. If you would like to donate a prize please contact nikki@rarecancers.org.au

The hike

Where is the meeting place for the start of the climb/hike?

The starting point for Kosi Challenge is in the courtyard of the Alpine Bar in Thredbo Alpine Hotel. Address: 8 Friday Dr, Thredbo NSW 2625.

How long does the hike take?

The summit is 2,228 metres above sea level. Everyone starts at the same point. For approximate times, please check out the following map:


Merritts Nature Track & Mt Kosi Track (walkers)

Valley Terminal to Summit is a 10.5km climb or 21km round trip. You will climb 4km to Eagles Nest and continue the 6.5km to take you to the top!

Eagles Nest (chairlift)

Eagles Nest to Summit is a 6.5km or 13km round trip. You will get a chairlift to the Eagles Nest Lookout and will walk the entire 6.5km to the Summit.

Those wishing to take the Chairlift option must choose a start time from 9.00am onwards, as the Chairlift will not be open prior to 9.00am.

Please note: the climb from the base to the summit is quite strenuous, so please consider purchasing a chairlift ticket if you are not at an adequate level of fitness. Those doing the full climb and who want to come down on the chairlift are required to purchase a chairlift ticket.

How long do we spend at the top?

The view from Australia's highest point is spectacular! With current COVID restrictions, however, only 100 people are permitted on top of the summit at any one time. Your guide (wearing a high vis RARE vest) will advise when it's time to move on.

If you are taking the chairlift down, the last chairlift is scheduled for 4.00 pm.

Please remember that you are hiking in the high country, and conditions can change very quickly. While great care is taken to keep participants safe, including having medics on hand, it is up to every climber to be responsible and avoid dangerous behaviour. This includes not climbing on the cairn at the summit.

How far is the hike?

You can choose to start from Valley Terminal for the 21km round trip or walk from Eagles Nest for a 13km round trip.

We’d like to run some of the walking track, is that OK?

National Parks forbids running on the metal walkways, which can be bouncy and slippery and may endanger other participants.

Are there any pre-event training sessions?

As people come from far and wide for this event, we won’t be organising team training sessions this year. We suggest you undertake your own personal training for the event. It would be wise to include some hill climbing, walking on an incline on a treadmill or stair climbing to stimulate your climbing muscles!

Do I have to be really fit?

The Kosi Challenge is quite challenging. Should you doubt your level of fitness please consult your GP prior to registration.

Will there be water and toilet stops?

There is a small café at Eagles Nest where some items can be purchased. Toilet facilities are available at Eagles Nest and also at Rawsons Pass, which is 800m from the summit. We advise all participants to come prepared with at least 1L of water.

What to bring

What should I wear/bring along?

The weather is highly changeable on any given day, so please come prepared for all weather conditions. This includes sturdy walking boots or shoes that have been worn in, waterproof jacket, light woollen jumper or fleece, long sleeve top, thermal top, gloves, warm hat and sunscreen/sunglasses. You should also bring at least one liter of water, lunch, snacks and any medication you may need.

Do we BYO lunch? Can we buy it?

Lunch, snacks and water can be purchased at the Village prior to the event.

What’s the best footwear to wear? Are runners/joggers Okay? Or hiking boots?

The weather is highly changeable on any given day. Please come prepared for all weather conditions. It is recommended to wear footwear that has already been worn in to avoid sore feet and blisters. Ideally, this would be hiking boots, but runners/joggers are also OK.

Do you provide sunscreen?

Please bring your own sunscreen, medications and weather gear.
