Question: Who are the owners of the stadium at which Mark Palmer played his only match at senior state level ?

 Having previously played for the state colts team, Palmer's sole match at senior state level came against Sri Lanka, during its 1989–90 tour of Australia. Mark Brendon Palmer (born 10 February 1967) is a former Australian cricketer who played a single List A match for Western Australia during the 1989–90 season.  From Perth, Palmer played at state under-16 and under-19 level, and played several matches as wicket-keeper for the Australian under-19 cricket team during both the 1985–86 and 1986–87 seasons.  He went on to attend the Western Australian Institute of Sport (WAIS), participating in its cricket program.  The match, played at the end of Sri Lanka's tour, was the first of a two-part series, with both matches held at the WACA Ground in early February 1990.  Western Australia trialled several new players in both matches, with Palmer one of four List A debutants in the match, alongside Brendan Julian, Chris Mack, and Darrin Ramshaw.  Replacing usual state wicket-keeper Tim Zoehrer, Palmer was bowled by Rumesh Ratnayake for a golden duck, but took two catches in Sri Lanka's innings, off the bowling of Peter Capes and Steve Russell.  He did not play at state level again. <SEP> Kenneth Edward "Ken" Lilly (born 25 December 1959) is a former Australian cricketer.  From Perth, Lilly played several matches for the state colts team from the early 1980s onwards, but did not make his debut at senior level until the 1988–89 season, when he was aged 29.  A right-arm fast bowler, he played two Sheffield Shield matches late in the season, as well as a single match in the limited-overs FA Insurance Cup.  Lilly made his first-class debut against Victoria in January 1989 at the WACA Ground, taking 3/72 in the first innings and four wickets for the match.  His second (and last) first-class match came against New South Wales the following month.  He took two wickets in the match, but finished with an economy rate of 5.48 from his 21 overs, failing to bowl a maiden.  Lilly's only one-day game at state level came between his two Sheffield Shield matches.  He took 1/19 from five overs, helping to dismiss Tasmania for 121 runs.  Lilly did not play at state level again, with Western Australia's fast-bowling stocks including several Australian internationals, notably Terry Alderman, Ken MacLeay, Chris Matthews, and Bruce Reid.  However, he remained active at grade cricket level, and later coached North Perth, where he was involved in the establishment of a trophy commemorating former state player Mark McPhee. <SEP> Peter Henderson (24 April 1965 – 28 February 2010) was an Australian cricketer who played a single match for Western Australia.  Born in Mount Barker, Western Australia, Henderson represented Western Australia at under-19s level, and later attended the Western Australian Institute of Sport.  His sole match at state level came during the 1987–88 McDonald's Cup, a limited-overs knockout competition.  In the match, played at the WACA Ground in March 1988, Henderson was part of a pace attack that included Terry Alderman, Ken MacLeay, and Chris Matthews, but failed to take a wicket, recording figures of 0/50 from 9.1 overs.  At grade cricket level, Henderson played 15 seasons for the Scarborough and South Perth Cricket Clubs, captaining and winning club champion awards at both clubs.  Bowling right-arm medium pace, he led Scarborough's wicket-taking for the 1987–88 season, taking 60 wickets.  Henderson died in February 2010, with his name commemorated in the Peter Henderson Memorial Trophy, which is contested between Scarborough and South Perth. <SEP>  The stadium's name derives from the initials of its owners and operators, the Western Australian Cricket Association. The WACA (formally the WACA Ground) is a sports stadium in Perth, Western Australia.
