The event saw members of the Perth-based Hong Kong community march from Queens Gardens to Elizabeth Quay dressed all in black to support those who have been voicing their opposition to the bill over the past weeks and months.

Hong Kong chief executive Carrie Lam on Saturday suspended the legislative process on the controversial extradition bill - an amendment to existing agreements - but said it would not be withdrawn.

In dramatic clashes this week, Hong Kong police have fired on protesters with tear gas and rubber bullets to try and disperse the crowds, which at times numbered more than an estimated 1 million.
