Australian seats have recently changed. new Infa Secure Neon/Comoressor and Sns Compaq/Lifestyle have high RF markers for children around 90-95Cm to RF (difference is body to leg ratio). SnS are starting to change their markers on other seats. These seats are now tested by the manufacturers to 15kgs in anticipation of Standards change which will allow for RF longer to these size/weights. There is no Type D Rf to 4yrs seats though.
Cabriofixi have used to 80-84cm RF (their head can go to top of this seat). For further RF you would probably need to get a Scandinavia type RF to 4yrs or larger seat like the Britax Multitech.
Eta if you hunt down Lenats31 Lena on the web and find where she is currently posting she will be able to give you better advice about ERF seats in the UK. She is from Denmark. Previous poster of EB.
