From 2007, Dynamix lived and worked in Berlin before returning to Australia. From 2008, he used the name MDX, as he was "starting a clean slate with new ideas and musical output, but reverted back to using the name MARK DYNAMIX around 2013." He established a record label, Long Distance Recordings which houses artists such as Namito, Deepchild, Danny Bonnici, Jaytech, Nick Galea, Mortlock. His new venture on the label with Danny Muller called THE ANTIPODEANS recently had success with their reworking of the ICEHOUSE classic "Hey Little Girl" with track reaching number 2 on the iTunes Electronic Albums chart in Australia (the single was classed as an EP meaning it entered the album chart). The song was remixed using the master stems with full permission from Iva Davies and is an authorised release.

In May 2019, he relocated from Sydney to Melbourne. In February 2021, due to the continuing COVID-19 lockdowns in Melbourne, he relocated from Melbourne to Brisbane.
