He had been performing at a nightclub before allegedly assaulting the woman, in her 20s.
Filly, 29, was moved to Perth after the arrest, where he now has to report to a police station daily after stumping up $100,000 AUD (£51,000) for bail.
The embattled rapper faces four counts of sexual penetration without consent, three counts of assault and one count of impeding a person’s normal breathing or circulation by applying pressure to their neck.
“While I understand many of you want my reaction on it, as this is an ongoing court case I hope you guys understand that I can’t and won’t be commenting on it publicly, so yeah I’ve just come on here to basically let you know the reasons as to why I can’t. Love.”
And fellow creator AngryGinge, real name Morgan Burtwistle, said: “I’m not going to pretend nothing has happened. I’m going to be open and honest as I always am. Where do you start?
“Four o’clock in the morning I’m laying in bed, I see what’s going down on Twitter. First of all I’m the exact same as you. I’m shocked. Um, yeah. You know, mental. Mental.
“But he’s now obviously involved in legal proceedings and I can’t comment on legal proceedings. You know how it is. Mad.”
He was born on August 6, 1995, and moved to the UK from Colombia when he was two years old.
Filly then relocated to southeast London during his childhood.
When asked what it was like growing up in the capital, he told Indy100: “I come from the bottom of the barrel…and that’s why I’m so grateful for the position I’m in now.
“My mum definitely shaped me with the lessons she taught me.
“She’s a single mum with three kids, my dad was a s*** dad so she just had to make it happen.
“She did loads of cleaning jobs. My mum worked at Poundland at the time I had some mad BBC series…just getting my mum out of the position she was in was just the biggest motivation.â€
Filly is best known for being a member of the comedy group known as The Wall of Comedy.
He is affiliated with fellow YouTuber Chunkz and the pair have collaborated on many videos and tracks.
