Tourism Australia told us:

“Our hearts and prayers go out to the family and friends of the two people who tragically lost their lives early this morning. According to information shared this morning by Australian police, this was a tragic but “isolated incident” carried out by a known criminal. Despite the tragic events of this morning, Australia remains one of the world’s safest, friendly and welcoming destinations to visit. The city of Sydney remains open for business today and authorities have urged people to continue with their usual business.Only the immediate area around the incident in Martin Place (pictured) is closed.”

And from TTF CEO Margy Osmond:
“These events have been very distressing to all Sydneysiders and, indeed, to everyone watching events unfold around the world. Our thoughts and sympathies are with the people who have been affected by these events.
“Sydney is a fundamentally safe city and will continue to be an iconic destination for visitors. The tourism industry will pull together and offer our support to help our great city recover from this tragedy.”
