https://www.abc.net.au/news/2018-11-10/security-strengthened-after-terror-in-bou...Authorities said there would be an increased police presence around the Melbourne CBD and at major events in the coming days so the public could feel comfortable going about their business, but they did not believe there was an ongoing threat.
Mr Ashton said the Myer department store's Christmas windows opened last night and other key events were being held this weekend, and he said there was "no ongoing threat at the moment".
"We have a number of events going on in Melbourne, Stakes day at Flemington, soccer at AAMI Stadium and also Remembrance Day so we are doing security reassessments in light of those events.
"At this stage we are encouraging people to go to those events and there will be additional police over the weekend."

Victorian Premier Daniel Andrews strongly condemned yesterday's attack and thanked police as well as bystanders who courageously stepped in to try to help.
"This is an evil and terrifying thing that has happened in our city and state today and we condemn it," the Premier said.
"Victorians can be assured that every member of Victoria Police … are equal to the task and will do everything they can in any circumstance to keep Victorians safe."
Victoria's Opposition Leader Matthew Guy also denounced the attack.
"I'll never accept that violent extremism should be a way of life for a big city like Melbourne," he said.
"All the resources of our state should be directed towards keeping Victorians safe. Victorians would say we do not have to live like this."
Prime Minister Scott Morrison attacked the "radical and dangerous ideology of extremist Islam" that inspired Shire Ali.
"I am the first to protect religious freedom in this country, but that also means I must be the first to call out religious extremism," he said.
"Religious extremism takes many forms around the world and no religion is immune from it. That is the lesson of history and sadly modern history as well.
"But here in Australia, we would be kidding ourselves if we did not call out the fact that the greatest threat of religious extremism in this country is the radical and dangerous ideology of extremist Islam."
Mr Morrison said Australia's terror threat level would remain at "probable".
The Prime Minister is due to take further briefings from security and other relevant agencies in Canberra later today.
'Don't let fear dictate'Road blocks in the area are expected to remain in place until at least mid-morning and members of the public are asked to avoid the area on Bourke Street between Russell and Swanston Streets.
Police have asked the public to submit any images or video footage of the attack to help them with their investigation.
Authorities said it was normal for people to have strong emotional or physical reactions after such a distressing or frightening event, and people should seek help from their doctor or by calling a helpline if they needed support.
Melbourne's Lord Mayor Sally Capp sought to reassure the public and praised the police for their swift response.
"Melburnians should feel reassured of the swift reaction from our police and emergency services who were so quickly, effectively and bravely at the scene dealing with the situation and minimising harm to the public," she said.
"I hope that we can pull together as a community to really support each other."
Trauma specialist Rob Gordon urged the Melbourne community to learn from the incident and be aware of dangers, but to also not let fear dictate.
"We need to understand and become familiar with risks and hazards," Dr Gordon said.
"Unfortunately the present time has got hazards of this sort where people take in to their minds to attack innocent people.
"It's very important to recognise that we live with all sorts of hazards but we do it successfully by being aware and understanding and careful.
"Fear doesn't help you get more prepared — it makes you jump at shadows and then you tend to get overwhelmed or exhausted and then you shut off."
