The Matildas continued to fine tune ahead of the Women's World Cup in Canada as they defeated Vietnam behind closed doors in Parklea, NSW on Tuesday.

All four goals came from different sources, Steph Catley and Caitlin Foord finding the back of the net inside the opening half an hour before Kyah Simon, in her 50th international appearance and Michelle Heyman struck within a minute of each other early in the second half.

The two teams will meet again on Thursday night at Jubilee Oval in Kogarah in the Matildas' official farewell match before the squad departs for Canada on Saturday.

After a period of dominance, the Matildas broke the deadlock in the 17th minute when Catley unleashed a cracking drive into the top corner. Foord then slotted home clinically to double the lead after a fine build up.
