The qualifying competition sees the fourteen lowest-ranked teams divided into four geographically-based groups with the teams in each centralised group playing in a round-robin league format. The winner and runner-up of each group will qualify for the next year's AFC U-16 Women's Championship finals.
Both teams went into Friday's match at the Rizal Memorial Track and Football Stadium on three points after opening round wins, with Myanmar defeating hosts Philippines 2-1 and Australia cruising to a comfortable 5-1 defeat of Thailand.
The game remained goalless until ten minutes from the interval when midfielder Isobel Dalton broke the deadlock, before a second from skipper Jessica Waterhouse five minutes later and Sunny Franco's first of the match on the stroke of half-time gave Australia a three-goal cushion.
Australia had to wait until the 79th minute to extend their advantage through Ayesha Kirby, who entered the fray nine minutes earlier as a replacement for first goal scorer Dalton, before Franco sealed the win in the last minute with her third of the qualifiers following her goal in the opening victory over the Thais.
Australia will look to end with a 100% record on Sunday when they take on the Philippines, whose chances of qualification ended after going down 6-1 to Thailand in Wednesday's later match at the Rizal Memorial Stadium, while the Thais and Myanmar face off to see who will join Australia at the AFC U-16 Women's Championship finals.
