The SRWTP was formed by on 10 January 1989 by Emile Brunoro, a two-time federal election candidate who contested the electorate of Fraser at the 1984 and 1987 elections.[10] It was officially registered with the Australian Electoral Commission (AEC) nine days later on 19 January.[11] Brunoro was also a member of the Residents Rally and a former member of the Rainbow Alliance, which were both also contesting the election (although the Rainbow Alliance later withdrew and joined the Fair Elections Coalition).[12][13]
It appears Brunoro may have got the idea for the party from Michael Boddy, who published a food column in The Canberra Times on 1 January 1989 where he wrote:
In fact, if someone would bring a bit of sense into the coming self-government elections and start an SRWT party, dedicated to banning the gas-coloured fake tomato forever from the ACT (an acronym you can't eat), I'd be in there boots and all with my support for such a civilised and civilising move.[14]
1989 election
Just as Boddy had called for, the SRWTP advocated for a ban on "gas-coloured fake tomatoes" from the ACT.[5][15]
In February 1989, Brunoro commissioned opinion polling with Billy Bong Research, showing the SRWTP with 3.7% of the vote.[16] The results were rejected by ACT Labor Party leader Rosemary Follett and Liberak leader Trevor Kaine, with Kaine stating that: "The Sun-Ripened Warm Tomato Party notwithstanding, I think people will see that [the election is] not a joke".[17]
Following the election, federal Liberal Party MP David Hawker attempted to ban "irreverent political party names" for the next ACT election, but the amendment was unsuccessful after the federal Labor government opposed it on the basis that "it would be too difficult to define mischievous in a legal sense".[21]
However, party registration laws were changed in the ACT, which now required that parties have 100 members and a formal constitution before being eligible to register.[22] Although the SRWT applied for re-registration, it was rejected by the AEC because it could not prove it had 100 members, and the party was formally deregistered on 23 November 1991.[1][22]
