Yeppoon is a great part of the country...I am house sitting just south of Wagga Wagga, but I will be heading north soon. I got a 5 month house sit 2 hours north of Wagga starting in April. So still land locked. I just got myself a big 4WD, so I am hoping to get into some Murray Cod and Yellow Belly soon.
That sounds like an interesting app. I haven't looked at. I will check it out. Cheers
