How much will it cost to send a 4-5kg package to Australia, Brisbane and how long will it take

I’m sending it from a rural area, (malingshan, Xinyi, in jiangsu province, China). I’m trying to decide whether I can meet the package in Brisbane, where I’ll be for a few days (up to nine days from sending date), or if I should send it straight home. Also, will weekends and holidays alter the time taken
