The centre of Melbourne has been brought to a virtual standstill as an estimated crowd of 170,000 marched through the city’s streets in a massive Union-organised “Change The Rules” protest as part of a larger campaign for better wages and conditions for Australia’s workforce.

The Change The Rules march in Melbourne, spearheaded by the ACTU and the Australian Unions groups, sparking remarkable scenes as a sea of humanity marched from Trades Hall in the city’s northern end, down to Flinders Street Station, where crowds filled the intersection to capacity and brought the entire area to a shuddering halt. The march attracted an estimated crowd of around 170,000; around 20,000 more than prior projections had estimated.

Change The Rules organisers even managed to sort out an AC/DC cover band for the event, who followed the march on the back of a flat-bed truck, mimicking the actual band’s iconic video for Long Way To The Top.

Victorian Premier Daniel Andrews was on hand for the Change The Rules march, leading the crowd down Swanston Street and posting a message of solidarity on social media shortly afterwards.

Simultaneous marches were held across Australia today, with tens of thousands turning out for the Sydney march.

Change The Rules protests were also held in every major city, as well as a raft of regional centres across Australia including Wollongong, Gladstone, Cairns, Mackay, Rockhampton, Launceston, Devonport, Shepparton, Wodonga, and Newcastle to name just a few.

The marches are being held as part of a broader Union-backed push for more stable wages for Australian workers, as well as a general raise of the minimum wage that sits more in-line with the rising costs of living in Australia. Which, frankly, is something just about everyone can get around.
