The honest answer to when you should fly Shenzhen to Perth is mostly about weather and demand at the far end. On three years of daily observations at the arrival airport, Apr-May, Sep-Oct gives the most comfortable combination of temperature and rainfall in Perth.
Averages below come from three full years of daily readings at Perth’s main airport, not from a seasonal generalisation. The warmest month is February (average high 34°C), the coolest is July (average low 9°C), and the wettest is August (172 mm).

Perth keeps the same clock time as Shenzhen, so there is no adjustment to plan for and the date you choose is purely about weather and price.
We publish observed fares for this route when we have them, and say nothing when we do not — there is no estimate on this page. What holds regardless of the route:
Midweek departures are consistently cheaper than Friday and Sunday on most routes, because that is where demand sits rather than because of any pricing trick. Where we have observed fares for Shenzhen–Perth, the weekday breakdown appears further down this page; where we do not, we leave it out rather than estimate it.
