After beating Wales twice in two games in Wrexham, Dave Connell's squad finished off a busy international window with this game that was affected by strong windy conditions.
Ireland were the better of the two teams in the early exchanges but there was a lack of real cutting edge chances in spite of their positive play.
Upon returning for the second period, Connell made four changes which included a debut for Isobel Ryan, who has impressed for Athlone Town recently in the SSE Airtricity Women's Premier Division.
Ireland had a couple of excellent chanes to take the lead with substitute Hannah Healy rocking the crossbar with a stinging effort from a long-range effort that deserved more.
Shamrock Rovers forward Joy Ralph then crashed a header back off the woodwork before defender Kate Thompson also went close but ultimately could not covert.
On 84 minutes, Halliday found herself in enough space to get the goal for the home team that decided this contest but the result will not take from the performance of the visiting team.
Next up for the Under-19s is their UEFA European Championship qualifiers against Belgium, Netherlands and Faroe Islands where they aim to advance to the next stage.
