This is similar to what is there in India during summer. Isn't this more problemematic in Australia because of ozone layer depletion [1]?

Yes, CFCs (Chlorofluorocarbons, the molecules that destroy the ozone layer) are also strong greenhouse gases, but they are present in such small amounts that their effect on global warming is negligible.
In the case of the ozone layer, we took action in time and the ozone layer is repairing well [1].
(Somewhat coincidentally - also from the same source - I just learned that warmer global temperatures actually inhibit ozone layer depletion.)

The long heatwave problems, exhaustion, dehydration, exacerbated fires and so on might be exacerbated in some parts of the country but not to a great extent. If you take the usual precautions (sunscreen, hat, etc.) you shouldn't see an effect.
