Very nice indeed , may I suggest a sprinkle of the very talented Garry G's GRF , them Auz Station / object sets would look nice here .On the Industry side He is updating his Auz Industry set at the Moment , nice sheep chain . On the Light house side why not use the Lighthouse set , great variety . viewtopic.php?t=59534
Transport not sure , Garry G has Auz trains ..... need thinking , definitely need Marine and Aircraft Grf . Town set , maybe a mix of sets .
That's my little ideas , look forward to the finish scenario .
