Both the MG4 and Dolphin will be released in Australia (my country) within the next couple of months but you can order them here now.
The base MG4 is A$38990....125kw., 250nm., 51kwh battery, 350km. range, 0/100kph. 7.7 seconds.
The base BYD Dolphin is A$38,890...70kw.,180nm., 44kwh battery, 340km, range, 0/100kph. 12.2 secs.
What were BYD thinking at that price....no competitition and the only thing in the favour of the base Dolphin over the similarly priced MG4 is that it has all the features such as Sat Nav, blind spot monitoring, cross traffic alert, front parking sensors etc. etc.
The similarly priced higher spec Dolphins compared to the higher spec MG4 are a different story and may sell well in Oz as they are quicker with many more features but time will tell I suppose.
