Jonathan's mum, Joyce Adebanjo, said her son was a "nice guy" and a "peaceful person". She is now in contact with other drowning victims' loved ones to prevent further deaths and improve signage around the river.What's wrong with the signage then?
She added: "A smartphone was bigger than the signage there.
"Nothing has been done to prevent these deaths in the most dangerous part of the river.Apart from all the warnings, the previous deaths, the expectation that people take responsibility for their criminally-stupid actions, you mean?
"I'm working to start a class action with other families who have lost relatives in the river.
"Next week I am meeting with a mum who lost her son near to where Jonathan died. We are going to come together. It's someone's child, someone's brother who has died.
"I want something to be changed. My son is not going to be a statistic."He already is. Nothing's going to change that.
A sign located around five metres from the ladder where Jonathan entered the water indicated that people had previously drowned in the basin, the hearing was told.No point putting up more signage for Darwin Award winners to ignore.
