I will present Australia’s contribution to international geodetic VLBI and its links to the radio astronomy community. While the core products mainly find their way into enabling sciences such as the world’s most precise coordinate frame, more recent applications of VLBI can be found in upcoming space missions (e.g. ESA’s NovaMoon) or intercontinental time and frequency transfer. Current risks and challenges will also be discussed, such as the rapidly increasing man-made radio emissions in space caused by providers of internet via satellites. Improved protection of VLBI frequencies on a global scale is an urgent need if we want satellite services being able to continue operations. This is where science meets policy and international treaties and I will report about current work on this matter at the national level.
