Foreign Minister Julie Bishop believes UK Prime Minister Theresa May was speaking on behalf of the British people when she said there has been too much tolerance of extremism.
Standing outside 10 Downing Street, Ms May declared the three terror attacks in the last three months were part of a trend which sees terrorism breeding terrorism.
After speaking to her foreign counterpart Boris Johnson, Ms Bishop said the attack which began on London Bridge on Saturday was an example of the new reality in which we live.
"But we must never accept it,' she told ABC radio on Monday.
"We both observed how this mindless savagery is striking into communities; it's designed to shock but that the British are resolute in their determination to defeat Islamist terrorism."
Asked about the response of Ms May - who insisted "enough is enough" - Ms Bishop said the British prime minister was expressing the views and opinions of the people she serves.
"The British people have been living with this for some time and I think Prime Minister May expressed the views of many British people," she said.
"Likewise in Australia, we will continue to do everything we can to keep Australians safe and to stamp out terrorism."
Defence Minister Marise Payne said Australian authorities were focused on reducing the lure of violent, extremist ideologies and working to stop people from choosing violence to express their views.
"We have to be lucky all of the time - those who we seek to prevent from these sorts of actions need to be lucky only once," she told ABC radio.
