Talk to you local Council. That looks like a significant level change from roadway and you are likely to have a problem with footpath. That would need to be dropped as you can’t have much cross fall on the footpath.

It looks very steep from the road level to your front boundary. I would be having a chat with council first about a new crossover, as it will be a big disruption to their gutter, footpath and their land. If they are happy to accept the principle you will need to engage a surveyor to work out the levels to see if it can be designed to be usable. Are there any other adjacent crossovers and driveways that could act as a precedent?

Instead of trying to access the SLOPING front yard on a busy road, enquire through the council and neighbours to who owns the property that your land backs onto. the neighbours home, from the aerial photo, shows a driveway which may of been a rear laneway many years ago. This driveway would go directly past your back yard. Who owns that land now? Ask your local council. you may be able to have rear access into your property.
