INDONESIAN authorities have arrested three men who they believe to be linked to the attack that killed seven people in the country's capital city yesterday.
The explosion site near a busy shopping area and UN offices remains cordoned off as police continue their investigations on Friday.
The tragic event has been claimed by Islamic State group and five of those killed were attackers. Two civilians, including a Canadian, and a police officer were also killed while another 20 were wounded.
Depok area police chief Col. Dwiyono told MetroTV that the three men were arrested at dawn on the outskirts of Jakarta.
Australia responds to terror attacks
The Federal Government's travel advice level to Indonesia has not changed following the terrorist attacks at Jakarta.
The Department of Foreign Affairs and Trade travel advice did not change from telling travellers to exercise a high degree of caution across the country, including Bali, because of the high terrorist threat.
An alert also remains in place for certain areas including Papua and West Papua, urging travellers to reconsider their need to travel.
Foreign Minister Julie Bishop told the ABC that experts had, for some time, predicted an attack in our part of the world.
She also said in a statement that the government condemned the attacks.
Opposition Leader Bill Shorten said Australia needed to keep working with Indonesia.
He said the majority of Indonesia's population was Muslim and said the Jakarta attacks should remind people that terrorism was not just against one religion.
"It's not a question of Christian versus Muslim," he said.
"More Muslims die from this sort of extreme terrorism than other people."
Attorney-General George Brandis said the Australian Government had offered Indonesia law enforcement and intelligence assistance.
