Machia lasted the duration and has now scored a goal in two outings for Ouriense, while Mozambique striker Lucia Jose was in action for the final 28 minutes after replacing Maria Baleia.
The result at Campo Luis Duarte keeps Ouriense second on the log with six points from two games in the relegation playoff round.
They will welcome leaders Estoril Praia in their next encounter on January 31 and Machia will hope to continue with her impressive goalscoring form in front of goal.
On the other hand, Ghana star Olivia Anokye featured in the final 34 minutes for A-dos-Francos after she replaced Joana Lucas but could not rescue her side from their first playoff defeat.
