The 21-year-old from Firhouse, Co Dublin, has remained in custody since his arrest during mass protests in the Egyptian capital four years ago.
Officials from the Irish Embassy in Cairo visited Mr Halawa yesterday and have said that he is in good spirits despite the delay in his release and is looking forward to returning to Ireland soon.
The authorities in Egypt have said that there is a process which must be followed in respect of all of the defendants in the trial and that there are a number of steps remaining to be gone through.
The Department of Foreign Affairs has said that Irish authorities have joined Mr Halawa's lawyers in "maintaining maximum pressure on the Egyptian authorities in relation to this process".
In a statement, the department said that Taoiseach Leo Varadkar has written to Egyptian President Abdel Fattah el-Sisi requesting that he expedite the process for Mr Halawa.
Minister of Foreign Affairs and Trade Simon Coveney has also been in direct contact with his counterpart, Egyptian Foreign Minister Sameh Shoukry.
A spokesperson for the Egyptian Embassy in Dublin said that they are doing everything in their power to expedite the release of Mr Halawa from prison.
They hope that they will make progress on this issue in the coming days.
