Hi everyone. I've made up this topology and just done everything that i could to make it work. The devices within its vlan can ping each other just fine but it cannot ping across the router. My theory is that there is something wrong with the serial DCE connection between routers. Any suggestion and help is appreciated thanks.

Hi @s3988111 ,
You need to enable ospf on the serial interfaces as follow:
Altona:
router ospf 100
network 222.22.2.1 0.0.0.0 area 0
Broadmeadows:
router ospf 100
network 222.22.2.2 0.0.0.0 area 0

Hi @s3988111
Just a reminder. Your PCs are not getting IP address, only the Printers and this is happening because the DHCP exclude address is not good.
Use this command here:
Broadmeadows:
ip dhcp excluded-address 192.47.89.1 192.47.89.5
ip dhcp excluded-address 192.47.89.65 192.47.89.69
ip dhcp excluded-address 192.47.89.97 192.47.89.100
Altona:
ip dhcp excluded-address 192.47.88.1 192.47.88.5
ip dhcp excluded-address 192.47.88.129 192.47.88.132
ip dhcp excluded-address 192.47.88.193 192.47.88.197
After that, you need to add route. If you are not familiar with Dynamic Routing protocol like OSPF, you can use default route like this:
Altona:
ip route 0.0.0.0 0.0.0.0 222.22.2.2
Broadmeadows:
ip route 0.0.0.0 0.0.0.0 222.22.2.1
