Hundreds of artists from New Zealand, the Illawarra, across the country, and even those who saved their paintings from flooded studios in the Northern Rivers, have donated paintings to the Art for Floods campaign.

The initiative is a follow-on from the Art For Bales campaign, which raised more than $160,000 in drought relief in 2018 and 2019.

This upcoming campaign kicks off from April 2 to April 3.

Shellharbour local and exhibiting professional artist Kathy Karas is one of 425 artists from around the country who have generously donated their artworks for online sales weekend #ArtForFloods.

Ms Hamann, co-founder of the initiatives, said it was an opportunity to raise awareness for a myriad of issues following the floods.

She said many friends and artists reached out to her about the extent of damages.

"The news cycle has moved on but the realities are that there will be huge homelessness [rates] out of this, huge social injustices and other issues," she said.

"But having 400 [plus] artists and their own followers, keeps it fresh in people's minds for longer."

There is a "full spectrum" of artworks from landscapes, traditional paintings, abstract florals and everything that people can choose from.

Some of the talents involved are Hawkesbury Art Prize winner Ben Tankard, Gosford Art Prize finalist Vanessa Encarnacao and Melanie Vugich, whose prints have featured in Oscar de la Renta's spring/summer '22 ready-to-wear collection.

All of the artworks are at different price points to cater to different budgets.

Proceeds from the initiative will be dedicated to three charities - GIVIT, NORPA and Arts Northern Rivers.

GIVIT work with community groups across the country to see what items are needed in different areas, and allow people to give funds for items, volunteer their time if they can or donate funds which will go directly to those who need them most.

Performing arts organisation NORPA, which was destroyed in the floods, provides the Lismore community with opportunities to pursue creative passions and get further training in the arts.

Arts Northern Rivers has been a peak arts body where residents can discover, and be a part of local exhibitions and performances.

Ms Hamann said "the full length of the Northern Rivers is painting" in this exhibition.

"I just find it unbelievable," she said.

Artworks will be advertised through the www.artforfloods.com website, where you can click on artist's Instagram pages and purchase artworks through there.

Ms Hamann said it was an opportunity for people to directly speak with artists and establish that rapport.

If you see an artwork on an Instagram page you like that is at a fixed price, you can comment 'SOLD' on the post to finalise the sale.

There are also artworks that will be auctioned - just bid above the reserve price and it will go to the highest bidder.

All payments, shipping and receipt details will be organised directly with individual artists.

You can start looking at artworks now before they officially go on sale on April 2 at 8am.

The sale finishes on April 3, and you can head to www.artforfloods.com to discover them all.
