Is the lockdown in Melbourne evaporating?

Is it just my imagination or is the lockdown in Melbourne evaporating even before it has been officially lifted?

There's a notable increase of people on the streets and a number of small shops are re-opening.  The local Coles supermarket is getting visibly busier.  And there are many more cars on the road than a week ago.  Some homeless people are back on the streets begging.  Parks are much fuller than they were two weeks ago.

I needed a haircut after making a total mess of cutting my own hair, and found a salon around the corner that had re-opened!  There is no law against them doing so but a few weeks back every hairdresser shut their doors.  This one was using the JobKeeper subsidy to keep their Australian staff at home and on the payroll, but getting the non-Australian staff, ineligible for assistance, to do the work.

Certainly, in all these instances, people were making some effort not to congregate and some distancing measures are in place going into shops, although in practice 1.5 meter gaps are really not practicable - the supermarket aisles aren't that wide and so people inevitably pass more closely than is recommended.

What are the implications of de facto lifting the lockdown before government advises it?  Does it undermine state authority?  Or is the state government turning a blind eye because the current infection rate and death rate is pretty low?

The state of Victoria has a population of 6.28 million, two-thirds of whom live in Melbourne.  According to the state government, as of 24 April 2020, the total number of coronavirus cases in Victoria was 1,343, including 6 new cases yesterday.  These are mainly people who have returned from abroad.  27 people are in hospital, including 11 people in intensive care. 16 people have died.
