The RAAF's FA-18 Hornets already fly high on Railway Terrace, tiny critters are enlarged on public housing on Bernard Street, and the 1998 flood is forever remembered on the main street.

Katherine even has a mural of The Man from Snowy River. What could possibly be left?

Psychedelically bats and half eaten mangoes enhancing the Salvation Army wall is the brainchild of Katherine High School senior, Chloe Forscutt.

It is Katherine's first youth led mural and Ms Forscutt's first solo mural.

Taking shape over the next four days, the mural, facilitated by Katherine Regional Arts, is just one of many school holiday activities taking place over the next two weeks.

"These murals create a sense of ownership and pride of a very public place in Katherine," Katherine Regional Arts executive officer Jacinta Mooney said.

Despite the sticky heat typical of the build-up, young people were keen to get involved in painting today, Ms Mooney said.

Icy-poles in one hand, brushes in the other, the youth got down to applying a white base colour to make way for the design.

"Chloe worked with well-known Darwin artist Dave Collins last school holidays, so we are thrilled to have her designing and implementing her first mural right in the centre of town this week," Ms Mooney said.

"It is a fantastic opportunity for a young person to have their own mural at just 17, it is not something that would likely happen in a larger city."

There are more than 35 activities laid on for Katherine's school holiday program, including discos, movie day, Muay Thai, pool days, arts and crafts and more.
