Can Dual Status Aliens Filing Jointly

My details are as follows
- I moved to the US from Australia on 06/18/2021 together with my wife.
- My visa is H1B and my wife is H4
- I have paid all my tax in Australia (AUS financial year is 1 July 2020 - 31 June 2021)
- I earned nothing regarding to US sources when I was in Australia
- I earned nothing from Australia during my stay in the US
 
From my understanding I am passing Substantial Presence Test and fall under dual-status-alien. Can I file tax married-jointly with my partner in this case? Do I need to file both 1040 and 1040NR for my case?
 
Kind regards,
Quan Vu.
