He outlined some of the key issues that the Socialist Alliance is taking into this campaign: "We want free education; we want free health care; we want a decent public transport system.
"We want an immediate transition towards 100% renewable energy.
"We want people to have access to decent public housing - housing is a right.
"We want to end all anti-worker and anti-union legislation and allow people to collectively organise and fight back for their rights.
"We want equal pay for women. We want equal marriage rights to be put immediately."
Jenkins addressed the issue of where the money will come from to pay for a socialist transition: "The question is where is that money going now. We already live in a society where the resources and material exist to have this transition made but it does exist in the bank accounts and in the hands of a very small number of corporations which are not accountable to the community."
"The only way we're going to see that change happen is when enough people - the majority of people - actively participate in reclaiming that wealth they they themselves have produced."
Socialist Alliance lead senate candidate Kamala Emanuel also addressed this theme. She said that if the four big banks were in public hands, that would give tremendous power of investment into the democratic hands of the people.
She pointed to the current campaigns of divestment from the big banks because of their irresponsible, profit driven climate polluting decisions. "Let's go a step beyond that," she said, "let's have that investment power in public hands, democratically run".
"Think what that could do for environmental repair."
She also highlighted Socialist Alliance's feminist politics and the need to end the gender pay gap. "We're very much in favour of pushing a vision of society where there is egalitarianism," she said.
Senate candidates Seamus Doherty and Farida Iqbal also spoke. Doherty spoke of the Alliance's commitment to justice and sovereignty for Aboriginal people and Iqbal spoke about the Alliance's campaign to support the Safe Schools Coalition and to win equal marriage rights.
The night also featured Chilean music and a message of solidarity with Chilean communities campaigning against the devastating ecological impact of industrial fish farming.
