Labor Party candidate Alannah MacTiernan ups the battle for the seat of Perth Alannah MacTiernan's billboard sits next to Liberal Party candidate Darryl Moore's office in Beaufort St, Bedford. Labor Party candidate Alannah MacTiernan. THINGS have become personal in the battle for the federal seat of Perth, with Alannah MacTiernan venturing into enemy territory to promote her campaign. Just over three weeks out from the election, the Labor Party candidate put up a new campaign billboard on the side of her opponent Liberal Party candidate Darryl Moore's office on Beaufort St in Bedford. Ms MacTiernan tweeted a photo of the building telling people to "keep an eye out" for the new billboard, adding, "Yeah we did!" It comes as Mr Moore also continues to work hard to be recognised in the community, appearing alongside campaign supporters to wave to drivers at a busy Inglewood intersection earlier this week. In June, Labor's Stephen Smith announced he was retiring after 20 years in Parliament and opened up the position. When Smith announced his retirement, the Liberals were rejoicing, believing candidate Mr Moore could win Perth. But the mood quickly deflated when former Labor minister Alannah MacTiernan announced her candidacy in July.
