Little penguins in need of more rehabilitation jumpers in case of oil spills. Penguin Foundation Officer Lauren Barker said the famously adorable little penguin was also highly susceptible to oil pollution.

"The last oil spill happened here in 2001 and it affected 438 little penguins," Ms Barker said.

"Thankfully 96 per cent of them were successfully released and penguin rehabilitation jumpers played quite a big part in that."

Oil can be fatal:

The Penguin Parade Visitors Centre on Victoria's Phillip Island has recently reopened after a $58 million upgrade and is calling on the public to help protect the much-loved little penguin.

When a little penguin is exposed to oil, it will stick to its feathers and the birds will try to preen and clean the oil off.

In doing so, they can swallow the substance and that can be fatal.

"So little penguin jumpers act as a rehabilitation tool. They are temporarily placed on the penguin and it stops them cleaning it off," Ms Barker said.

When they are rescued off the beach, they come here to the Phillip Island Wildlife Clinic where experts will put on a little-penguin jumper.

They will wear that temporarily until they can be washed, cleaned and then will recuperate at the clinic.

In 2014, an ABC News story on the Knits for Nature program was posted online and in response, the program received tens of thousands of little knitted jumpers.

Despite good intentions, many jumpers were the wrong size, shape, or had embellishments which were unsafe for penguins.

Although Phillip Island's penguins could not wear most jumpers, they were still put to good use by putting them on penguin plush toys to raise funds for penguin conservation, over the past five years more than $185,000 has been raised.

Phillip Island Nature Parks Wildlife Rehabilitation Officer Jodi Bellett said staff were thankful for the contributions.

"Tens of thousands were sent in from around the world and we were really grateful, but unfortunately most weren't suitable for penguin rehabilitation," Ms Bellett said.

1,400 knitted jumpers needed:

"The Phillip Island Nature Park has recently added a further 6.7 hectares of little penguin habitat that could house a further 1,400 penguins, so we're asking knitters to match that number with rehabilitation jumpers in case another oil spill occurs," Ms Bellett said.

"There's been lots of patterns and amazing creativity that has come out of these donations. Some of them have been exuberant.

"We've had capes, neck ties and all sorts of things which are wonderful and really do well in the sales department, but not so much for our little penguins that are oiled."

Avid knitter Lyn Blom has been making rehabilitation jumpers for years and said she never wanted to see penguins wearing them again.

"It is very sad to see them wearing a knitted jumper that I'd made because it meant that the penguin was uncomfortable, sick and needed our help," Ms Blom said.

Read the instructions:

Penguin Foundation Coordinator Jaquelina Alves-Ferreira collects the jumper donations and decides which ones are suitable for rehabilitation.

"People email me and express their interest in knitting some jumpers for the foundation and Ill send them the pattern, they will then send me the completed jumpers," Ms Alves-Ferreira said.

"Once they've sent them I'll sort them and if they are suitable for penguin rehabilitation, I'll send them over to the penguin hospital.

"If they're not suitable but they're really nice and colourful then I'll keep those for the kids or to sell them in the retail store."

Ms Alves-Ferreira said her favourite designs were jumpers with added decorations.

"There are a few fairy costumes that we've had sent in with little wings and tutus, and even come with a wand. My favourite is a teddy bear onesie with teddy bear ears and a little hoodie."
