She signed up for the 2016 Gibb River Postie Bike Ride in June.
Ms Ebbett and her husband Craig plan to hold fundraisers before the ride to help them raise $10,000 for Bright Blue.
Among the fundraisers are a quiz and auction night and barefoot lawn bowls.
Ms Ebbett said after working in the postal service for the past two years, she was excited to be able to use her job to help sick children.
“I am excited and nervous at the same time and looking forward to the event,” she said.
“I think it is a very worthy cause and can help adults too if cures can be found.
“We have fun events planned that will bring friends and families together while helping a good cause.”
