Anderson added that he'd always taught his children to "do the right thing" and to "look after people", which Anderson believes his son was doing on Sunday morning.
According to reports, Anderson was allegedly attacked by Flame in a Queenscliff park on Sydney's Northern Beaches after consuming alcohol and MDMA.
According to documents tendered to Manly Local Court on Monday, Flame fled the party after briefly losing consciousness, fearing he may have overdosed.
Court documents further state Liam begged Flame to stay and after he refused, Liam ran after him.
Police allege that Flame turned on Liam, kicking and punching him repeatedly, not letting up until police arrived and subdued him with capsicum spray.
Detective Inspector Michael Boutouridis called the scene "quite bloody".
"Liam was trying to help him," Anderson told the publication.
"He was such a decent human being."
