The"givealittle"fundraising page set up for Waghorn has yielded more than $100,000 from more than 1800 donors.
Waghorn,a marine biologist,thanked her carers and family,saying there had been"a lot of blood,sweat and tears put into getting me where I am today".
"I am fairly mobile now,albeit wobbly and minus some strength,"she said.
"I am slowly regaining the use of both of my hands - my right is worse than my left. But I'm working on that everyday ... I'm doing really well."
She said her arms,hands and a small portion of my stomach were grafted on December 11 with her back and buttocks the donor sites.

Waghorn said this proved to be quite"uncomfortable"given that her back and butt were"harvested"a second time,along with some strips from my upper thighs.
"By this stage,I'd been[painfully] upright only twice between these two graftings,with a lot of assistance from my beautiful physio,family and a handful of nurses.
"So there was a lot of blood,sweat and tears put into getting me where I am today after my final graftings."
The eruption has killed 21 people to date,including 14 Australians.
Another 26 were injured by the deadly ash clouds,with many still in hospitals in Australia,New Zealand and the United States recovering from their burns and other injuries.
Two American tourists now recovering in the US have shared a happy photo of them taken on Whakaari/White Island just before the eruption buried them in"hot volcanic ash".
Ivy Kohn Reed and Rick Reed were critically injured in the eruption and were cared for at Auckland's Middlemore Hospital.
Rick suffered burns to over 30 per cent of his body,including his hands,legs and face.
Ivy received burns to 20 per cent of her body,including her hands,face and right leg.
Ivy shared a picture of herself and Rick on the island just before their"lives changed forever".
"Approximately 15 minutes after this was taken,the White Island volcano erupted,burying us in hot volcanic ash and toxic gases,"Ivy wrote on fundraising page Go Fund Me.
"We survived,were rescued and spent almost eight weeks in a New Zealand hospital receiving critical care treatment."
Ivy said their dream vacation quickly turned into a nightmare.
"The next year will be the hardest of our lives while we try to rehab and regain as much functionality as possible."
