The minister is in Paris for a meeting of the counter-Daesh coalition, alongside representatives from France, the US, United Kingdom, Italy, the Netherlands and Germany.
"We also are very keen to grow the numbers participating in the coalition ... it needs many shoulders to the wheel and all of us who were here today will be reinforcing that with our colleagues more broadly," she told reporters.
