It states *insert SC/APC*, presuming it’s a fibre optic port, however, next to my NBN box (am Australian), there is no port from the wall similar to the one in my room on the same level as me. I presume the fibre optic came is already connected in the NBN box as the string like line on the right hand side of it? I have the newest model of NBN. FTTP connection, one story house, with a garage downstairs, wanting to know if I can buy a converter from fibre optic cable to Ethernet to my PC?

I had to use an Allen key to show what the inside of the port looks like.

I have no idea what that box is. Maybe it was from a previous fiber install. All the means is the physical type of fiber connector it wants.

In general you can't connect stuff to the fiber used by the ISP. The biggest issue is fiber is only the physical media. They use many different methods to encode the data into the lasers being used. The most common is something based on GPON. This word though only represent a massive number of valid selection they can make. There are also many variations in the number and color of the lasers they are using.
I suspect this is intentional so they can control what device can be connected to their network. In most countries you can't even buy your own device you can connect to fiber.....it seem in india you can.

So that is only the start of the reason you can't connect to the ISP fibers. You talk about a fiber ethernet converter. These have been around more than 20 years but they are completely incompatible. They use ethernet rather than GPON to encode the data.

Pretty much the only way to use any kind of fiber inside your house is if you control the equipment on both ends. You would really only see someone use it to connect remote buildings on their property when this distance is to far for ethernet.

you could connect a fibre modem to this port provided by your ISP or bought seperately
so maybe the room you are at was rented to someone who connected a modem with separate plan from the owner

Interesting. So I could buy a more modern modem than my housemates Belong dwa0122bln as it seems to be bottlenecking with my Launtel 1000/50 plan on a 5ghz network off peak times to have it connected to the fibre optic port, (obviously needing to buy the green tipped fibre optic cable) and it should still connect with our ISP (Launtel) and act as the second router? Or does that need to be re-configured by myself or Launtel through their servers?

I did forget to mention that in relation to the scenario about a potential previous housemate having their own seperate ISP, how would this correlate since that person would need to have their own modem with their own ISP connected to the UNI-D 2 port physically using WAN connection or can the ISP virtually have this overrided or can the NBN do so?

I find this quite interesting, thanks for sharing.
As my housemate who owns the property, does not want me to feed the Ethernet cable to the modem (around 5 meters in length) from my room to the NBN box and the modem, I believe if I find a compatible fibre optic cable to Ethernet or something along those lines, it will still feed signal to the NBN box. I will need to open the cover of the NBN box to see if that fibre optic cable is currently in use however, as if it isn’t, then no electrician has installed anything and the connection is not live.
 
You have 2 problems I suspect. First that box on the wall if it is a fiber termination point then you would have to hope the fiber coming into it is actually connected to the ISP network.

The second one is the messy issue of have 2 ISP connections in the same house. Some ISP do not allow it...end of project. Makes it hard when you say have 2 apartments in 1 house. So if the ISP will allow it then it likely comes down to money. If you are willing to pay a second monthly charge you likely can have your own internet connection. The ISP will provide you with a box to connect to the wall outlet. It is highly unlikely they will allow 2 modem/ont connected under a single account without a extra charge. Partially this is because they actually don't know where these modems are connected. You could take them over to your neighbors house and hook it to a unused fiber port and then split the bill
