Australia Temporary Residence

Hi,

I am a Temporaray Resident and on partner visa. Working full time in Sydney for years. Could you please advise the following

- I will be travelling from Sydney to Hong Kong and then from Hong Kong to Macau in April. I aware that I will need to apply visas for both. Just wondering could I apply for both at the same time? Or I need to have it for Hong Kong granted before applying for Macau's?
- Do I sumbit both applications in person to Chinese Consular office in Sydney?

Thanks
Jessica
