On 9 May 2008, a Boeing 737-800 made a low go around at Perth in good daylight visibility after not approaching with regard to the temporarily displaced runway threshold. A second approach was similarly flown and, having observed a likely landing on the closed runway section, ATC instructed a go around. However, instead, the aircraft flew level at a low height over the closed runway section before eventually touching down just beyond the displaced threshold. The Investigation found that runway closure markings required in Australia were contrary to ICAO Recommendations and not conducive to easy recognition when on final approach.
