Mr Richardson is among a group of plumbers and electricians who tackled the Kokoda Track last week to raise funds and awareness about depression and suicide.
The group has so far raised more than $69,000 in addition to the $125,000 they raised last year for beyondblue in a bid to raise awareness, empathy and support for those suffering from depression.
Mr Richardson said he was pleased to have surpassed his target of $5000.
People wishing to support to him can donate at www.beyondbluefundraising.org.au/event/kokodachallenge until the end of next month.
