On Tuesday they were mobbed at Sydney airport before their flight to Melbourne, on which they were cheered and clapped by the Qantas crew.
For the singing siblings, who make up the duo Brentwood, it was a ''strange'' experience.
The pair made it through to the top seven of X Factor Australia before being one of two acts cut in Monday night's live double elimination.
For the past several weeks the pair, who grew up in the Wakatipu, have had a taste of reality and been holed up in either the X Factor ''mansion'' or the studios where the live shows are performed, largely away from the public eye, Ms Brentwood (29) said.
''[Tuesday] was really probably the first time we'd been out ... [it] was the first taste of that that we got outside of the competition and it is really surreal.
''Finley and I just looked at each other and went 'Oh, God, what's happening?'
''For us, getting our names out there was important because we feel like we've got a) some really good music that we want to show people, and b) we feel really strongly about a few issues that we're hoping to be able to talk about in the public eye and it's really awesome that our profiles are building so that we can get a chance to talk about that ... to a bigger audience.''
One of the causes close to the siblings' heart was mental health, in all its forms, spurred on after their father took his own life in 2011.
While they hadn't been approached by anyone, they were keen to become advocates for mental health, Mr Brentwood (26) said.
''We just feel so strongly about it that we can't not speak up.
''We just want to help the public mood shift towards addressing the problem, and that really begins with opening up and sharing our story because so many people are affected by mental health - not just depression and anxiety; across the whole platform.
''It's so rife within our community, we can't not talk about it because that's where the problem lies,'' he said.
Aside from advocacy work, the pair also planned to focus on finishing their EP of original songs and were looking to maximise the opportunities being on the TV show had offered them.
''We met some incredible people up there who were, like, 'right, when you're ready give me a call; this is what we want to do' ... we're really excited about that and we just want to get into it, basically,'' Ms Brentwood said.
''But it will just be about us making our own music and putting it out there and you never know who's watching - at the moment there are a lot of eyes on us, so hopefully the right people see us and things might really skyrocket from here, and we're really hoping that that happens.''
The pair were criticised at times for the songs chosen for them by coach Iggy Azalea. Ms Brentwood said they ''didn't get any say in that regard''.
''We probably would have loved to have had a little bit more of the creative say as to how the songs were arranged. We might have changed things up a little bit more, but we were really, really happy with how they all turned out,'' she said.
While they had a busy couple of months ahead, they were hoping to return to Queenstown in January or February for a ''summer holiday'' and have not ruled out a cameo appearance at one of Arrowtown's Blue Door's open mike nights.
