The frequency for FIA 120.0 SE of Melbourne was changed to 123.35 earlier this year, if that's the area you are referring to.
For MB Ground I don't know why they selected a frequency so far displaced. The usual convention for GA towers is to try and allocate frequencies in the low end of the aviation band e.g. 118 - 124MHz.
Sound like they didn't consult/alert whatever RAPAC is called these days.
