    $\begingroup$ If I'm not mistaken this is Brisbane airport (YBBN). Brisbane has a notorious problem with wasps building nests inside the tubes so much quicker than at other airports, so these covers are put on even for short turnarounds. $\endgroup$

The things hanging on the left and right side of the nose are pitot covers. They cover the pitot tubes located here:

Pitot Tubes

(Boeing 737 Airplane Characteristics for Airport Planning)

The covers are there to protect the narrow inlets from contamination or blockage:

Pitot tubes are normally covered when the aircraft is parked for more than a short period of time to reduce the chance of blockage or contamination.

(Pitot Static System on SYKbrary)

They are usually painted red and have REMOVE BEFORE FLIGHT written on them:

The cable connected to the right side of the aircraft (left on your image) is the ground power cable. You can see it larger in this image:
