Willow warriors activities are funded / sponsored in a number of ways:

The New South Wales Department of Environment and Climate Change through the Environmental Trust along with the New South Wales National Parks and Wildlife Service (NPWS) are the major sponsors of the Willow Warriors group.

They provided the funds for the "Willows Out of Wollemi" project, which was managed jointly by Friends of the Colo (FOC) and NPWS.

During this project over $30,000 was invested in whitewater equipment and treatment and mapping tools to carry out the work. The WOW project started with Willow treatment and has progressed to map, treat and monitor many other invasive weeds along the Colo River and it's tributaries within the Wollemi National Park. As the equipment is not needed every weekend by FOC and there is a close relationship between Willow Warriors and Friends of the Colo, Willow Warriors also uses, and makes additions to, the pool of equipment on willow control projects across New South Wales and the ACT.

The NSW Environmental Trust provided 2 grants to FOC 2001-2004 $84,000 and 2004-2007 $39,000.
In 2008 the New South Wales Environmental Trust approved a grant of $98,800 to Willow Warriors to implement a willow mapping and monitoring project across South East NSW. The funding will go to raising public awarenss arround the issues with invasive willows species, reimbursing volunteers travel costs, hiring river guides and keeping the stakeholders informed of our progress in mapping, monitoring and the treatment of the invasive willows. 

The National Parks and Wildlife Service provided over $20,000 in seed money in 2000-2001 for the Willow out of Wollemi project the funds covering the costs to start the willow treatment, provide training and to purchase some equipment. NPWS also provides logistical support for the projects by assisting with access to NPWS estate, mapping tasks, storing the equipment and administering funds. NPWS hosts the Friends of the Colo nursery where they grow long stem native tubestock from local provenance seed for the Colo, Grose and Hawkesbury River catchments

 The Hawkesbury Nepean Catchment Management Authority (H-N CMA) sponsors all landcare groups in the Hawkesbury Nepean Catchment by organising and paying for Landcare insurance. This is a significant contribution to the landcare groups not just because they have organised a group insurance and so reduced the premium and then also paid the premium, but also because this reduces the administration burden on our volunteers. The H-N CMA also funds specific projects to reimburse volunteers costs, and purchase Roundup and tools or to hire contractors.

The National Heritage Trust through Australian Government Envirofund has provided grants for two Willow Warriors projects:
The Lower Grose River Black Willow control project 2007-2008 received funding of $5000 for a black willow treatment and monitoring project. This funding covered the administration costs including the costs of contacting landowners, training, purchase of roundup and equipment maintenance and the purchase of native tube stock where re-vegetation was required.
The Goobarragandra River invasive willow control project received $12,000 for monitoring the Goobarragandra River for black willows and treating crack willows where we have landowner consent down to the Kell's Lane Bridge. This funding covered similar costs to the Grose project but also included the funds to run a trial project to remove the larger willow debris after treatment.

The Sydney Catchment Authority has provided $8,000 to fund the willow treatment project along the Wingecarribee and Wollondilly rivers with the focus on treating the Crack Willows in the Wallaby Rocks section of the river, downstream of Berrima township. The grant is to cover the costs of contacting landowners to gain consent for the work, reimburse volunteers travel costs to the treatment days and hire river guides to manage the on water safety. This section of river flows through a rocky, narrow and scenic gorge that provides very exciting whitewater rafting although the willows are straddling the river in several places.

The Australian Department for Families, Community Services and Indigenous Affairs, has provided a grant of $3000 to Willow Warriors to purchase an EPIRB and 5 sets of camping gear (sleeping bag and thermarest plus two tents and a hammock) so that new volunteers who do not own equipment can try out overnight activities before investing in all the gear.

Penrith Whitewater Stadium (PWS) is a significant corporate sponsor for the group. PWS assist the group with volunteer safety in two ways. They run whitewater awareness sessions for the group so that new volunteers can learn a little about whitewater water rafting and self rescue, they also get to experience paddling and swimming in whitewater so they can make an informed decision about participating in activities before going to remote locations only to find they are outside their comfort zone. Secondly they organise the rafting guides whom we hire from them when we are paddling higher grade sections of rivers. This logistical support not only eases the burden on our committee and activity leaders but also improves the safety for volunteers.

Australis Canoes supported the Friends of the Colo group on our first trip in 2000 by lending us 14 Bushman Canoes which where helicoptered into the Colo gorge for the 28 volunteers and NPWs staff to paddle out to Upper Colo over the 5 days treating the black willows. It was the fun had and the results acheived during this activity that lead to the Friends of the Colo and subsequently Willow Warriors being formed. These groups have gone on to control invasive willows in the Colo Catchment and work on the control in other catchments across south east NSW. We have 4 Bushman Canoes that we use on the flat water sections of rivers we monitor for willows.

The Hawkesbury City Council, Tumut Shire Council and Wingecarribee Shire Council have also supported the group by assisting us with contacting landowners and providing access to council managed land.
